Neandertalensis is not a direct ancestor of H. Sapien. H. Sapien is a hominid branch that will become an evolutionary dead end. H. Sapien and H. Neandertalensis did not occupy the same geographic region.

Answers

We can infer from the information in the table below information about the evolution.

Evolutionary History of Modern Man

1) Modern shares a common ancestor with gorillas and chimpanzees.

2) Some species before sapiens sapiens, according to the evolutionary process, are:

AustralopithecinesErgasterRectusNeanderthalensis and  sapiens.

3) Australopithecines inhabited the arboreal savannas of Africa around 2.8 to 2.3 million years ago.

4)Several species of australopithecines were able to walk upright or semi and had small brains.

5) During this period, Africa was undergoing a series of environmental changes that transformed its arboreal savannas, inhabited by australopithecines, into open savannas.

6) Thus, the australopithecines began to be exposed to predators, due to the decrease in shelters. This fact led to the extinction of most australopithecines.

Only a few lineages were able to adapt and survive, allowing the emergence of hominids.

With this information, we can know a little more about the evolution process of the human species.

Answers

Answer:

yes, these are isotopes of nitrogen.

Explanation:

Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.
